Help?

Jannike
I'm in my third month of taking the Pill. At the end of the first two months, my period came two days early, two days before the week off the pill. I figured this was normal since I'd just started taking them and my body still had to get used to them. Now, in the third month of taking the pill, I'm still 8 pills away from the week off and I've started bleeding. I don't know if it's my period or spotting but I'm a little concerned. Is this normal? Or is this some kind of sign that my body isn't reacting to the pills as it should? What should I do? Help?
